Inside, the capsule's sole passenger would ride in a near-standing position, wearing a G-suit to help force blood to the head during acceleration. The passenger's head would sit in a transparent hemispheric dome topped with an aerospike for better supersonic performance. It gets better.

Dimensions of the capsule's cabin area are roughly two feet (diameter) by 7.5 feet (length). There will be no room in the capsule for movement once the vehicle goes weightless. After launching to 100 miles, parachutes will be used to slow the final descent.
